Description

Technical Field

[0001] This application relates to the field of heavy media coal preparation technology, and more specifically, to a fully intelligent material rotary tillage and spreading machine. Background Technology

[0002] Heavy media coal preparation is a gravity-based coal preparation method that uses a heavy liquid or heavy suspension with a density greater than water and between that of coal and gangue as a medium to achieve separation. Heavy suspension coal preparation, commonly known as heavy media coal preparation, is widely used in production.

[0003] Because the media powder is piled up in an irregular sandy mass when it enters the warehouse, and there are frozen blocks and caking phenomena in the media powder, the electromagnetic chuck will have uneven suction when picking up the material. Large pieces of material in the caking and frozen blocks cannot be picked up, and small pieces of material will be fed into the blockage after being picked up. This directly causes the concentration and density of the heavy suspension to fluctuate continuously and significantly, and the density stability of the sorting medium is out of control. Ultimately, it interferes with the sorting accuracy and production continuity of the heavy media sorting system. Summary of the Invention
